Getting that bike down the track isn't too difficult, its getting OFF the throttle and keeping it upright and straight thats tough!! When you get outta the throttle on one of those, all the inertia in the rear wheel basically reverses...can start a SERIOUS case of the shakes... once that happens, all you can do is hold on and close one eye...(you need to keep one eye open to TRY and see where your gonna end up!!!) Got a customer that runs a Pro Alcohol drag HD...FUN stuff!
